摘  要

　　　從蒙自一小選礦廠周邊采集土壤在基礎培養基中加入0.028mg/ml的硫酸鋅分離純化出一株細菌。運用火焰原子吸收分光光度法測定該細菌對鋅的吸附力，結果顯示該細菌對鋅具有吸附力。繪制出該細菌的生長曲線并對該細菌進行一系列生理生化試驗，試驗顯示：革蘭氏染色呈陽性，能水解淀粉，過氧化氫酶試驗呈陽性，唯一性碳源試驗可以利用葡萄糖、蔗糖、甘油、不能利用乙酸，在37℃時生長良好。

關鍵詞：細菌；鋅吸附力；生理生化

ABSTRACT

　　　Mengzi around a small processing plant from the soil collected in the basic medium supplemented with zinc sulfate 0.28mg/ml of a bacterium strain isolated and purified。Using flame atomic absorption spectrophotometry of zinc absorption in the power of bacteria, the results showed that the bacteria have the absorption edge of zinc。And the bacteria in a series of physiological and biochemical tests, tests showed: Gram-positive, can hydrolyze starch, catalase test was positive, the only test you can use carbon sources of glucose, sucrose, glycerol, can not use acetic acid At 37°C when growing well, and draw out the bacterial growth curve.

Key words: bacteria；Zinc adsorption force； Physiological and biochemical
